LC8955
No.3215–2/4
Decoder Block
The decoder block converts the ADPCM data into 16-bit linear PCM data. Decoding parameters can either be set by the
CPU, or read from subheader information in the ADPCM data stream.
DAC Interface Block
Two output formats are available. The first is suitable for input to SANYO’s LC7833, 7833M DA converters, and the
second is the standard CD-I format. The output circuit will also accept CD-DA format input data and, by setting an
LC8955 internal register, switch it through to the output pins without processing.
